Excellent tutorial, helped me with a project

[@NachiketaHebbar]

Thanks !

[@movie_cinema938]

can i use mobile hotspot

[@oscarperalta8581]

Bro, I cant download the program to the board, please help me, we have de same nodemcu board

[@NachiketaHebbar]

What error is it showing in arduino ide? Make sure you have installed board manager for Node Mcu, which is in the description.

[@sumukhanadig]

Hey good video, but I'm trying to control 2 servo motors with different sliders on the app, and pins D7 and D8.
It doesn't work. Both motors work fine.. Please help

[@riteshkapoor4589]

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
WHAT SHOULD I DO??

[@universal4334]

Bro do you know how to set a remainder with out rtc..like using library

[@creativeashok3469]

Bro how can I control bldc motor using node mcu

[@sobhitdas3071]

sensational bruh

[@Saini_Classes]

this problem is come why Invalid library found in C:\Users\hp\Documents\Arduino\libraries\servo: no headers files (.h) found in C:\Users\hp\Documents\Arduino\libraries\servo

[@NachiketaHebbar]

Did you install it from sketch->Include libraries

[@jwkooi]

Nico project! Can I copy-past the Sketch from somewhere? I'm going to try this and also try to connect it to Google Home mini. Maybe later try to make a universal remote controller, so I can control my CD-player and other things which are not smart but have a remote controller. To turn it on, I will use Sonoff.

[@NachiketaHebbar]

I have included the Github link in the description

[@NachiketaHebbar]

Good luck with the project. You can try using IFTTT as a platform as well, to connect google assistant and node mcu.

How can I control more than 1 servo using node mcu.

[@NachiketaHebbar]

1)Just in arduino code, create 2 servo objects using line Servo servo1 instead of Servo servo.
2)We control servo using servo.attach(D4) . So attach new 2nd servo motor to another pin(say D5) and write servo2.attach(D5). Rest everything remains same.Take care of Vin and ground.
3)Now you can control any motor by simply writing servo1.write or servo2.write

[@ayushsinha7416]

Error( servo was not declared in the scope)

[@ayushsinha7416]

1)I have changed Servo servo to Servo servo2.
2)written //servo2.attach(D5);//NodeMCU D5pin after //servo.attach(D4);//NodeMCU D4pin

[@ayushsinha7416]

@@NachiketaHebbar hey bro can you please help.

[@NachiketaHebbar]

You are doing servo object declaration wrong. Check this link to see how 2 servo motors are integrated in blynk :

[@chamdaracay3122]

any tutorial on how to make a esp8266 code??

[@NachiketaHebbar]

You can check my video on getting started with Iot in node mcu . czcams.com/video/LHWrhWIoj0I/video.html

[@vinayKumar-cs9tj]

BLYNKWRITE library is not highlighting

[@NachiketaHebbar]

It doesnt get highlighted in some versions of arduino. If it is showing error, make sure it is installed correctly .

[@DS3d_printing]

bro please make a video using joystick instead of slider
Bro please make a video on controlling the brushless motor controller using blynk
